Abstract

Procedure for obtaining disazo dyes of the formula **(See formula)** wherein Me means a metal atom and the A and/or B rings may be further substituted, characterized in that 1 mol of a 4,4'-diamino-3,3'-dimethoxy-or -3,3'- Tetrazotized dihydroxydiphenyl is coupled with 1 mole of 2-hydroxynophtelin-6,8-disulfonic acid and 1 mole of 2-hydroxynephtelin-3,6-disulfonic acid and the obtained azo dye is treated with a metal transfer medium.
